Caption

a, Biological neurons connect through synapses using chemical messengers transmitted between presynaptic and postsynaptic neurons. b, The charge-trapping MOS capacitor consists of multiple layers stacked on a silicon substrate. Under illumination, this device exhibits non-volatile charge trapping and a change in capacitance, functioning as a memcapacitor. c, The adaptive LIF neuron model consists of input spikes as a current source, a leaky resistor, and an optoelectronic memcapacitor device. The light-modulated memcapacitor influences the neuron’s adaptability and the pattern of generated output spikes.
